I will be lifting first thing in the morning followed by cardio. It is my only choice.

PreWO meal, My plan is 1/2 cup of oats or brown rice 45 min - 1 hour before the gym.

Should I add a 1/2 to 1 cup of a pure orange juice for some simple sugar energy, or will that be too much to deplete to have an effective cardio session? I am cutting.
